EDIT: I almost forgot. I did notice a fair amount of input lag when moving the mouse cursor on this screen. We just browsed the web and played Flatout: Ultimate Carnage so we didn't get into any twitch-based shooters that would make this really noticeable. I'm hoping its just related to some of the frame smoothing or noise reduction settings.

Any ideas on which settings we can adjust to reduce any input or processing lag?

it could be some image "enchacement" but it could be simply inferior design. try turning all features off.
